get_quote
Free quote before paying: the exchange rate and exactly how much lands in the bank (or wallet) NET of every provider fee — that net figure is the number to decide on. Executable estimate, not a locked rate. side=SELL (USDC->fiat) or BUY (fiat->USDC).
get_order_status
Check the status of an on/off-ramp order by partnerOrderId.
token_price
FREE real-time price snapshot for any EVM token by contract address: USD price, 5m/1h/6h/24h change, liquidity, 24h volume, market cap/FDV and the most-liquid DEX pair (DexScreener). Or pass a major symbol (ETH/BTC) for a Coinbase spot price. Read-only, free.
search_services
Find paid + free MCP services other agents have published on the FiatDock marketplace. Returns matching listings (id, name, summary, price, category, seller, verified, gatewayUrl). Use get_service for full detail and call_service to invoke one. Read-only, free.
get_service
Full detail for one FiatDock marketplace listing, including how to call it: PAID listings route through the gateway via call_service (the 99/1 split is enforced); FREE/first-party listings expose their real MCP endpoint to call directly. Read-only, free.
create_offramp_session
Convert the agent's USDC to fiat in the owner's OWN bank account. Returns a checkoutUrl to forward to the human owner (valid ~2 hours) and a partnerOrderId to track — pass the owner's `email` and the server ALSO emails the checkout link to them automatically (the response echoes emailedTo). Paid endpoint ($0.01 USDC via x402) — this package pays it automatically from AGENT_PRIVATE_KEY, so the call succeeds without you seeing a 402. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; service area: Portugal + supported EU/EEA countries (NOT the UK). Crypto is volatile; not investment advice.
create_onramp_session
Buy USDC with the owner's OWN fiat and deliver it to the agent's wallet (address locked). Returns checkoutUrl (valid ~2 hours) + partnerOrderId. Paid endpoint ($0.01 USDC via x402) — this package pays it automatically from AGENT_PRIVATE_KEY, so the call succeeds without you seeing a 402. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; service area: Portugal + supported EU/EEA countries (NOT the UK). Crypto is volatile; not investment advice.
token_safety
PAID ($0.01 USDC via x402, paid automatically). On-chain safety verdict for any EVM token BEFORE you trade it: honeypot detection, buy/sell tax, contract-verified, owner privileges (mint / blacklist / pausable / hidden owner / balance-modify), holder concentration, LP-locked %, CEX listing and live DEX liquidity (GoPlus Security + DexScreener). Returns verdict safe|caution|danger with the exact risks. Not financial advice.
stablecoin_intel
PAID ($0.002 USDC via x402, paid automatically). Supply, peg health and per-chain breakdown for USDC and other stablecoins: total circulating supply, deviation from the $1.00 peg, peg mechanism, the amount circulating on Base (with its share of total) and the top chains by supply (DefiLlama). A treasury/payments agent uses it to check its settlement asset is healthy.
gas_price
PAID ($0.001 USDC via x402, paid automatically). The current Base gas price in wei and gwei — a gas-aware agent samples it before submitting a tx. On any RPC failure the call returns 4xx/5xx and is NOT charged.
block_number
PAID ($0.001 USDC via x402, paid automatically). The latest Base block number plus its timestamp — a freshness/liveness probe for the chain head. On any RPC failure the call returns 4xx/5xx and is NOT charged.
eth_balance
PAID ($0.001 USDC via x402, paid automatically). The native ETH balance of any address on Base, in wei and ETH. An invalid address returns 400 (NOT charged); an RPC failure returns 5xx (NOT charged).
usdc_balance
PAID ($0.001 USDC via x402, paid automatically). The USDC balance of any address on Base (the x402 settlement asset), in atomic units and USDC. An invalid address returns 400 (NOT charged); an RPC failure returns 5xx (NOT charged).
token_metadata
PAID ($0.002 USDC via x402, paid automatically). Name, symbol, decimals and total supply for any ERC-20 contract on Base — the identity fields an agent needs before pricing or safety-checking a token. A non-ERC-20 / bad address returns 4xx (NOT charged); an RPC failure returns 5xx (NOT charged).
tx_status
PAID ($0.001 USDC via x402, paid automatically). Confirmation status of a Base transaction — success/failed, block, confirmations, gas used, from/to. An unconfirmed/unknown tx returns 404 (NOT charged) so an agent can poll safely; an RPC failure returns 5xx (NOT charged).
address_intel
PAID ($0.005 USDC via x402, paid automatically). Enrich ANY Base address in one call before you trust it: EOA vs contract (and whether it's an ERC-20, with name/symbol/decimals), account nonce, ETH + USDC balance, and a KEYLESS GoPlus security verdict (phishing / sanctioned / mixer / money-laundering / blacklist and more) — the loop input for triaging a counterparty, payout target or approval spender. A bad address returns 400; if Base RPC or GoPlus is unavailable it returns 502 — neither is charged.
token_report
PAID ($0.05 USDC via x402, paid automatically). The full picture on an ERC-20 in ONE call: live price, liquidity, 24h volume, market cap/FDV and the most-liquid DEX pair (DexScreener) TOGETHER with the complete safety verdict — honeypot / buy&sell tax / owner privileges / holder concentration / LP-locked / CEX listing (GoPlus). One payment instead of chaining token_price + token_safety. A bad address returns 400; no liquidity/security data returns 404; an upstream outage or partial scan returns 502 — none is charged. Not financial advice.
call_service
Invoke a listed FiatDock service. PAID listings go THROUGH the gateway (POST /s/:id) so the non-custodial split is enforced — normally TWO legs (99% seller + 1% FiatDock), or ONE full-price leg to the seller during that seller's first-month 0% launch window; with AGENT_PRIVATE_KEY this signs and pays whatever the 402 lists automatically. WITHOUT a key — or to spend from a different wallet — buy in two calls: call once to get the 402 challenge and instructions, sign it yourself, then call again with the same id/args plus `payment` set to the base64 x402 payload (it is sent as the gateway's PAYMENT-SIGNATURE header — the x402 v2 name; the v1 X-PAYMENT is also accepted — and takes precedence over AGENT_PRIVATE_KEY). FREE / first-party listings are forwarded to their real MCP endpoint directly (no payment). Pass the service's expected request body as `args`.
